The VisionScape Skateboarding Tech Demos encompass the prototype builds of two different skateboarding games pitched by VisionScape Interactive on the original Xbox. Both run on the RenderWare engine and share the same mechanics, assets and level design; some of which were recycled from a cancelled home console port of Rocket Power: Zero Gravity Zone, previously in the studio's pipeline.

The files themselves were recovered from an XDK unit whose contents were first outed on April 29, 2011 by ProtonX. Found alongside the builds presented below were several unfinshed and unrealized projects, namely: Speedmetal, an arcade racer featuring vehicular combat; Tiltronica, a pinball-themed car game; a Samurai Jack demo and various RenderWare-based samples originating from the SDK; among others.

The Sonic and Tech Deck prototypes were released by Borman on July 24, 2016 in the wake of a successful crowdfunding effort between Sonic Retro and ASSEMblergames.
